I drove to my parents' house at 40 miles per hour. If I had driven 30 miles an hour instead, then I would have gotten there 20 minutes later. How many miles did I drive?

48 miles

Step-by-step explanation:

40mph =

30mph = + 20 minutes

40-30 = 10mph which means that 10mph = 20 minutes

20 x 4 = 80 minutes - this is how long it took to drive 40 miles

80 mins =  1.2 hours

40mph x 1.2 to find out distance travelled as speed x time = distance

= 48 miles

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

207/8 is the right
