Answer:
A.
Step-by-step explanation:
d = rt
If t is the time taken by the train, then the truck takes t+2 hours.
For the truck:
d = 45(t + 2)
For the train:
d = 60t
Total distance travelled by both:
= 2d
= 60t + 45(t + 2)
= 60t + 45t + 90
= 105t + 90 where t is the time taken by the train.
The sum of 7 and 9 is:
7 + 9 = 16
The sum which is 16 is greater than 12. Therefore we add
3 to the sum:
16 + 3 = 19
<span>Therefore the correct answer to this problem is 19.</span>
This is multiplication. Simply do 3 times 4 and add the negative. The answer is -12
