Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
Jo-Bob hopped into the hot air balloon, released the anchor rope, and pulled on the lift chain, which ignited the flame and provided the warm air that caused the balloon to rise.  When the lift chain was pulled, the balloon would rise at a rate of 50 feet per minute.  But when the chain was not being pulled, the balloon would slowly descend at a rate of 10 feet per minute.  During his balloon ride, he pulled the chain for 15 minutes, then released the rope for 10 minutes, then pulled the chain for another 15 minutes, and finally released the chain and allowed the balloon to slowly descend back to the earth.  During his balloon ride, what was the highest elevation reached by the balloon?

### Response:
 Wakati Jo-Bob alipovuta kamba ya kusimamisha, kifimbo kilipanda kwa kasi ya futi 50 kwa dakika.
Wakati wa kuvuta kamba kwa dakika 15 za kwanza, kifimbo kilipanda futi 50*15=<<50*15=750>>750.
Wakati wa kipindi cha dakika 10 kinachofuata, wakati alipoachilia kamba na kifimbo kusimama tu, kifimbo kilishuka futi 10*10=<<10*10=100>>100.
Kisha, wakati wa kuvuta kamba kwa dakika nyingine 15, kifimbo kilipanda futi 50*15=750.
Hivyo, mwishoni mwa kuvuta kamba mara ya pili, wakati Jo-Bob alipoachilia kamba tena, kifimbo kilikuwa kimefikia urefu wa futi 750+750-100=<<750+750-100=1400>>1400 juu ya uso wa dunia.
