Hello there,

A car left Ottawa at 1 p.m. going at 35 mph. A second car left the city at 4 p.m. going in the same direction at 50 mph. At what time will the second car catch up with the first?

350/50=7

7+4=11

11:00 pm

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

what is the answer to this
