Answer 1

Answer:

1)15m/s

2)35m/s

Step-by-step explanation:

54 km per hour

1 hour = 3600 seconds

1 km = 1000 m

54 km = 54000 m

54000 m in 3600 seconds

by taking ratio of 54000:3600=15:1

so 15 m in 1 second

similarly,

126 km per hour

126000 m in 3600 seconds

by taking ratio of 126000:3600=35:1

so 35 m in 1 second
