Answer 1

2.98×10^-6 hrs

Explanation:

Speed = Distance/Time

Time = Distance/speed

Given

Distance = 17in

Speed= 90mph

Convert inches to miles

1in = 1.578 × 10-5 mile

17in = 17(1.578 × 10-5) mile

17in = 26.826×10^-5miles

Get the time

Time =26.826×10^-5/90

Time = 0.298×10^-5

Time = 2.98×10^-6 hrs
