Andrew Is riding his bike. He biked a distance of 14 miles at a rate of 7 mph. using the distance formula, d = rat, solve for Andrews time in MINUTES. (9th grade Algebra 1)

d = rt ( d = distance, r = rate (speed) and t = time)

14 = 7t

Divide both sides by 7:

t = 14/7

t = 2 hours

1 hour = 60 minutes.

2 hours x 60 = 120 minutes total.

120 minutes

Step-by-step explanation:

14 divided by 7 is 2 (hours). This means that Andrew biked for 2 hours at a pace of 7mph. Two hours is equal to 120 minutes.

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.
