Answer:
79.5 miles.
Step-by-step explanation:
From the question given above, the following data were obtained:
Average speed = 53 mi/h
Time = 1 hr 30 minutes
Distance travelled =?
Next, we shall convert 1 hr 30 minutes to hours. This can be obtained as follow:
Recall:
1 hr = 60 mins
Therefore,
1 hr 30 mins = 60 + 30 = 90 minutes.
60 mins = 1 hr
Therefore,
90 mins = 90 mins × 1 hr / 60 mins
90 mins = 1.5 hr
Finally, we shall determine the distance travelled during the time. This can be obtained as follow:
Average speed = 53 mi/h
Time = 1.5 hr
Distance travelled =?
Average speed = Distance travelled / time
53 = Distance travelled / 1.5
Cross multiply
Distance travelled = 53 × 1.5
Distance travelled = 79.5 miles
