Question

A car travels 500m in 50s, then 1,500m in 75s. Calculate its averages speed for the whole journey

Answer 1

15m/s

Step-by-step explanation:

500 ÷ 50 = 10m/s

1500 ÷ 75 = 20m/s

10 + 20 = 30

30 ÷ 2 = 15m/s

Answer 2

Answer: 16 miles per second

Step-by-step explanation:

Find the total distance traveled and the total time.

`\text{average rate}=(1500+500)/(75+50)=(2000\ miles)/(125\ second)=\large\boxed{16\ mps}`
