Answer:
30 mph
Step-by-step explanation:
First we need to find the distance travelled in the first 1h30m.
We can do that multiplying the speed by the time travelled, so we have:
Distance1 = 50 * 1.5 = 75 miles
If the total distance is 120 miles, Michael still needs to travel 120 - 75 = 45 miles.
And if the total time travelled is 3 hours (10 AM - 7 AM), the second part of the travel has a duration of 3h - 1.5h = 1.5h
So if the distance is 45 miles and the time is 1.5 hours, we can find the speed of the second part:
45 = speed * 1.5
speed = 45/1.5 = 30 mph
Answer:
D. 25
Step-by-step explanation:
The left end of the baseline has measure (x-16). In this geometry all of the right triangles are similar, so the short-to-long side ratios are proportional:
(x -16)/12 = 12/16
x -16 = 9 . . . . . . . multiply by 12
x = 25 . . . . . . . . . add 16
The unknown length x is 25.
Answer:
18 gallons
Step-by-step explanation:
divide 300 by 15 you 150 or 15 again then add 1 gallon per every twenty miles
thus your answer is 18 gallons of gas
