Question

for a fighter jet to take off from the deck of an aircraft carrier, it must reach a speed of 62 m/s. what is the speed in miles per hour?

Please explain the best you can.

Answer 1

You need to do a few conversions.

m/s=meters per second

you want to get it into miles per hour.

i'd start by multiplying 62m/s to get it into hours, instead of seconds

you'd do that by multiplying by 3600. ( to minutes, then hours)

you'll have 223,200 meters an hour

to get meters into miles

just know that 1 mile=1609.34meters

divide and finish the conversions.

Answer 2

This might be a stupid question but how do you get 3600?

Answer 3

Second>>Minute>>Hour

1 secondx60=1 minutes x 60=1 hour

60 x 60=3600

Answer 4

Okay, sorry I was adding 60+60 for some reason. Thank you. I got 138.69 so to fit my answer choices I have I put it in scientific notation of 1.38 x 10^2 however, my only choice close to this is 1.4 x 10^2 would this be the answer?

Answer 5

Can you post all your choices?

Answer 6

A. 120mph B. 1.4 x 10^2 C. 8.4 x 10^3 D. 300mph

Answer 7

Definitely 1.4 x 10^2. That is 140mph, which is very close to 138-139.
