• c. 14 mph
• d.196 mph

Answer : 4 mph

3. If it takes 12 hours to cover 120 miles, how much is the speed?

• a. 144 mph
• b. 10 mph
• c. 3 mph
• d. 24 mph

Answer : 10 mph

4. At a speed of 9 kph, how much distance can you cover in 23 hours? (Formula: D=ST)

• a. 207 kilometers
• b. 201 kilometers
• c. 197 kilometers
• d. 200 kilometers

Answer : 207 km

5. How long does it take to cover 182 kilometers at a speed of 14 kph?

(Formula: T = D/S)

• a. 15 hours
• b. 13 hours
• c. 11 hours
• d. 9 hours

Answer : 13 hours

Explanation

1.

Given facts

• Distance = 121 miles
• Time = 11 hours

To find out

• Speed

Formula

S = D ÷ T

Solution

S = D ÷ T

S = 121 miles ÷ 11 hours

S = 11 mph

2.

Given facts

• Distance = 28 miles
• Time = 7 hours

To find out

• Speed

Formula

S = D ÷ T

Solution

S = D ÷ T

S = 28 miles ÷ 7 hours

S = 4 mph

3.

Given facts

• Distance = 120 miles
• Time = 12 hours

To find out

• Speed

Formula

S = D ÷ T

Solution

S = D ÷ T

S = 120 miles ÷ 12 hours

S = 10 mph

4.

Given

• Speed = 9 kph
• Time = 23 hours

To find out

• Distance

Formula

D = S × T

Solution

D = S × T

D = 9 kph × 23 hours

D = 207 km

5.

Given facts

• Distance = 182 km
• Speed = 14 kph

To find out

• Time

Formula

T = D ÷ S

Solution

T = D ÷ S

T = 182 km ÷ 14 kph

T = 13 hours
