A speed limit of 100 kilometers per hour (kph) is approximately equal to 62 miles per hour (mph). Write an equation relating kilometers per hour, k, to miles per hour, m. Then predict the following measures. Round to the nearest tenth. a) a speed limit in mph for a speed limut of 75 kphb) a speed limit in kph for a speed limit of 20 mph
Accepted Solution
A:
1.) 75 x .62 = 46.5 I multiplied by .62 because the kph to mph ratio is 1:.62 2.) 20 x 1.6 = 32 I multiplied by 1.6 because that's how many km are in a mile.
