Question Help

lorasvet [3.4K]

Answer:

The speed of the boat is 20 km/hr

Step-by-step explanation:

Let s be the speed of boat in still water

Let d be the distance

Upstream speed = s-4

Jane took 30 min to drive her boat upstream to water-ski at her favorite spot.

So, Distance traveled in upstream = $Speed \times time =(s-4) \times \frac{30}{60}$

Downstream speed = s+4

So, Distance traveled in downstream = $Speed \times time =(s+4) \times \frac{20}{60}$

So, $(s-4) \times \frac{30}{60}=(s+4) \times \frac{20}{60}$

30s-120=20s+80

10s=200

s=20

Hence The speed of the boat is 20 km/hr

let inches of snow be x..

x=6 1/2-3/4

3/4+x=6 1/2

Explanation:

Convert 1/2 into similar denominator:

1/2=2/4=x2

3/4=3/4=x1

Convert into mixed number:

6 2/4=6x4+2=26/4

Subtract the terms:

26/4-3/4=23/4

Answer:

x=23/4 or 5 3/4.
