Answer:
50 miles per hour
Step-by-step explanation:
In this question, we are asked to substitute the information given into the equation. First we need consistency on units. Hence the 1hr 30 minutes is same as 1.5hrs
Now since d =rt
We need to get r = d/t
This means r = 75/1.5 = 50 miles per hour
You know because if you round to the nearest whole number for these numbers, you will have 13 + 3 + 5, which you know is greater than 20.
