LaTanya will walk (3 mi/hr) her bike from her house to the bike shop, which is 1.5 mi from her house, to get the bike

fixed. She expects to wait 30 min for the repair. Then she

will ride (10 mi/hr) her bike home. How long will it take

her to get home?

A)2.12 hr

B)2hr

C)1.15

D)4hr

1.15 hr

Step-by-step explanation:

Given that:

To get bike fixed :

Speed = 3 miles per hour

Distance = 1.5 miles

Time taken = distance / speed

Time taken = 1.5 / 3 = 0.5 hour

Waiting time for repair = 30 minutes = 0.5 hours

Return home :

Speed = 10 miles per hour

Distance = 1.5 miles

Time taken = distance / speed

Time taken = 1.5 / 10 = 0.15 hour

Total time : (0.5 + 0.5 + 0.15) = 1.15 hr

if you use photomath right away it will give you the answer not like this app that you have to wait for people.
