You are on a boat on the seine river in France the boat speed is 32 kilometers per hour the seine has a length of 764 kilometers

kiruha [24]

we are given

the boat speed is 32 kilometers per hour

so, speed is

$v=32km/hr$

the seine has a length of 764 kilometers but only 547 kilometers

so, the distance is

$d=547km$

now, we can find time

$t=\frac{d}{v}$

now, we can plug values

and we get

$t=\frac{547}{32} hr$ .................Answer

Amy is going on a 4 1 4 4 4 1 mile hike. She has already hiked 2 3 4 2 4 3 miles. How many more miles does she have left

serg [7]

Answer:

1 1/2 miles

Step-by-step explanation:

Amy is going on a 4 1 /4 miles hike. She has already hiked 2 3 /4 miles. How many more miles does she have left?

We solve the above question using the operation of Subtraction

The number of miles she has left is calculated by:

Total number of miles she must hike - Number of miles she has hiked

Total number of miles she must hike

= 4 1/4 miles

Number of miles she has hiked = 2 3/4 miles

Therefore:

The number of miles she has left to hike is = 4 1/4 miles - 2 3/4 miles

Lowest Common Denominator = 4

4 - 2 + ( 1/4 - 3/4)

2 + (1 - 3/4)

2 + -2/4

1 2/4

= 1 1/2 miles
