A person can walk 3 1/4 miles in one hour. How many miles can the person walk in 1 3/4 hours?

weqwewe [10]

Since Emily is walking at a constant speed, we can solve this using proportions, equating ratios of distance/time.

The first ratio is 3/4 miles/1/4 hour
The second ratio is 1 mile/ x hour

Equating the two ratios: 3/4 / 1/4 = 1/x
3 = 1/x
x = 1/3 hour

Car A travels 20 mph faster than Car B. In the same time that Car A travels 252 miles, Car B travels 196 miles. Find their speed

RoseWind [281]

Answer:

A = 70

B = 90

Step-by-step explanation:

We know that Car A travels 20 mph faster than Car B.

Assuming the speed of Car B to be x and the speed of Car A to be x+20, we can write:

$\frac{196}{x} =\frac{252}{x+20}$

Taking the reciprocal of both sides to make x the subject:

$196(x+20)=252x$

$196x+3920=252x$

$252x-196x=3920$

$56x=3920$

$x=70$ ---> speed of Car A

Finding the speed of Car B: $x+20 = 70+20=90$

Therefore, the speed of Car A = 70 and the speed of Car B = 90.

Answer: b) 8√2

Step-by-step explanation:

$64^{\frac{7}{12}}=(2^6)^\frac{7}{12}=2^\frac{6\cdot 7}{12}=2^{\frac{7}{2}}=\sqrt{\underline{2\cdot 2}\cdot \underline{2\cdot 2}\cdot \underline{2\cdot 2}\cdot 2}=2\cdot 2\cdot 2\sqrt2=\large\boxed{8\sqrt2}$
