Answer:
Step-by-step explanation:
Let the speed in the morning be s, then in the evening it is s - 4
<u>The distance is equal both directions:</u>
- 45 min *s = 1 hr 10 min *(s - 4)
<u>Time in hours:</u>
- 45*1/60*s = (1 + 10*1/60)(s - 4)
- 3/4s = 7/6s - 7/6*4
<u>Multiply all terms by 12 to clear fraction:</u>
- 9s = 14s - 56
- 5s = 56
- s = 56/5
- s= 11.2 mph
<u>The distance is:</u>
- 3/4*11.2 = 0.75*11.2 = 8.4 miles
The correct answer is 1.7 times 10^3.
A term that describes the fraction that has a variable or valuable expression proper factor
Answer:
5
Step-by-step explanation:
If X equals 2, then 3 times X would be 6. This is because if a number and a variable are put together, you have to multiply them. 6-1 is 5.
