Please help! How much is 840 miles in 3 & 1/2 hours?

Sagot :

I'm assuming your teacher wants you to calculate the speed

1/2 = 0.5

3 & 1/2 = 3 + 1/2 = 3 + 0.5 = 3.5

If a plane flies 840 miles in 3.5 hours, then,

speed = distance/time

speed = (840 mi)/(3.5 hr)

speed = (840/3.5) mph

speed = 240 mph

Answer: 240 mph
