Answer:

it  is 120 speed

Step-by-step explanation:

Answer 2

Answer:

Concept:

Distance travelled divided by time taken is the most commonly used formula for calculating average speed. If you have both the initial and end speeds, multiply them by two. The entire distance travelled is divided by the time interval to arrive at an average speed. For instance, someone driving 20 miles north and then 20 miles south in 40 minutes has an average speed of 40 miles divided by 40 minutes, or 1 mile per minute (60 mph).

Given:

1. Jojo rides on his motorcycle 55 kiloraeters in 5 Ya hours. speed in kilometers per hour?

2. If it takes 3.5 hours to drive a distance of 203 kilometers average speed?

3. What will be the average speed in km/h if the car travels 13km 30 minutes?

4. Cindy took a two-hour bicycle trip. If she traveled 31 kilon average speed?

5. The speed of train is 55 km/h, find its speed in meters per

find the answers for the given questions

Answer:

$1A:$ $distance = 55km$

$time= 5\frac{1}{2} hrs$

$find$ $average$ $speed$

$speed = \frac{distance}{time}$

$speed = \frac{55}{5\frac{1}{2} }$

$speed = 10 km/hr$

$2A:$

$given$ $distance$ $=203km$

$time=3.5hrs$

$speed = \frac{distance}{time}$

$speed = \frac{203}{3.5}$

$speed = 58 km$

$3A:$

$speed$ $of$ $a$ $car$ $is$ $13km$ $in$ $30min$

$speed = \frac{distance}{time}$

$distance = speed*time$

              $= 13*0.5 hr$

              $= 6.5 km$

$4A:$

$given$ $distance = 31km$

$time = 2hrs$

$speed = \frac{distance}{time}$

         $= \frac{31}{2}$

         $=15.5 km$

$5A:$

$1 km = 1000 m$

$55*1000 = 55000 meters$
