Answer:
2.98×10^-6 hrs
Step-by-step 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
