So 800/120=? (Here your answer will be in mi/min, unless you convert the minutes to hours (120/60=2)… then it will be in mph)

240/2.5=? (km/h)

While I could do the math for you, I think that giving you a basis for how to do it will help you in the long run if you run into more problems like that. Good luck, hope that helped.

Airplane: 400 m/h 800 miles / 2 hours (2 hours = 120 minutes) = 400 miles per hour

Car: 96 km/h 240 kilometers / 2.5 hours = 96 kilometers per hour

= 800/2 (120/60 = 2 to convert minutes to hours)

= 400 miles/hour

Speed = distance/time

= 240/2.5

= 96 kilometres/hour

800miles/ 120 mins ( or 2 hours)

=400 miles per hour (mph)

car 240 Km / 2.5 hrs

=96 Kilometers per Hour (Kph)

there are 1.6 km in a mile.

so 800miles/120minutes = speed in miles/min

and 240km/2.5hrs = km/hr
