1: distance: 238 miles time: 5 hours, 24 minutes, find the average speed. 2: distance: 446 miles time: 17 hours, 48 minutes, find average speed. 3: distance: 387 miles time: 12 hours, 54 minutes, find average speed.

Step-by-step explanation:

speed = distance / time

1. (238 mi)/(5.6 h) = 42.5 mph

2. (446 mi)/(17.8 h) = 25.0561... mph . . . (a very long repeating decimal)

3. (387 mi)/(12.9 h) = 30 mph

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.
