Answer:
A- 7.4 ⋅ 10−4 mm
Step-by-step explanation:
Well, to solve this problem, we must convert the number and / or the units in a more imaginable one.
We are given two choices:
a. 7.4 x 10^-4 mm
b. 7.4 x 10^4 mm
Converting the units and numbers into meters and general form, respectively. (What is meant by general form is not to write it in scientific notation).
a. 7.4 x 10^-4 mm (1 m / 1000 mm) = 0.00000074 m
b. 7.4 x 10^4 mm (1 m / 1000 mm) = 74 m
Now comparing the two values above, what do you think is the distance between the tracks on a DVD? Definitely NOT 74 m or else the DVD is extremely big. Therefore the correct is the smaller one.
Answer: 50 miles per hour
Step-by-step explanation:
Find out the length of the normal route.
Distance = Speed * time
= 48 * 40/60
= 32 miles
The detour is 8 miles longer so the length is;
= 32 + 8
= 40 miles
What speed should he travel at to make it in 48 minutes. Remember speed is in miles per <u>hours</u>.
Speed = Distance/ time
= 40 / (48/60)
= 50 miles per hour
