Michael drove his car for 150 minutes at a constant speed of 75 miles per hour and then for another 2 hours at a constant speed of 81 miles per hour. How far did Michael drive? Show or explain how you got your answer.

Hello! 150 minutes is equivalent to 2.5 hours, because there are 60 minutes in 1 hour and 30 minutes is a 1/2 hour. 150/60 is 2.5. First, let's find how far he went on the speeds he went. He went 75 mph for 2 ½ hours. 75 * 2.5 is 187.5. Then, he went 81 mph for 2 hours. 81 * 2 is 162. Add both numbers up. 187.5 + 162 = 349.5. Michael drove 349.5 (349 ½) miles.

187.5+162=349.5 miles

150 minutes is 2 and a half hours you would multiply 2.5 and 75

then you would multiply 81 by 2 then finally add both of the answers together
