Therefore using distance formula, we get:
Distance = Minimum speed × Time
Distance =
Distance =
Therefore, distance traveled at this speed is 237.6 km.
Question 8:
Maximum speed (S) = 121 km/hr
Time taken (T) = 3.3 hours.
We know that, distance traveled is equal to the product of speed and time.
Therefore using distance formula, we get:
Distance = Maximum speed × Time
Distance =
Distance =
Therefore, distance traveled at this speed is 399.3 km.
