a motorist goes 78km in 40minutes calculate it speed
78 km / (40/60)hr = 117 km/hr
To calculate the speed, you need to divide the distance traveled by the time taken.
First, you need to convert the time from minutes to hours since speed is typically measured in distance per hour.
40 minutes is equal to 40/60 = 0.67 hours (rounded to two decimal places).
Next, divide the distance traveled (78 km) by the time taken (0.67 hours) to find the speed:
Speed = Distance / Time
Speed = 78 km / 0.67 hours
Speed ≈ 116.42 km/h (rounded to two decimal places)
Therefore, the motorist's approximate speed is 116.42 km/h.
