Rehan rides a bike along the edge of the park. It takes him 4 hours. What is his average? (length= 15km, width=5 km)
a) 10 km/h
b) 8 km/h
c) 6 km/h
Continues ratio of a : b = 7 : 9 and b:c = 6 :13 is…………
a) 40 : 62 : 134
b) 42 : 54 : 117
c) 44 : 62 : 139
d) 46 : 54 : 132
Continues ratio of x : y = 2.7 : 5.4 and
y : z = 6.3 : 9.9 is…………
a) 7 : 14 : 22
b) 17 : 24 : 32
c) 27 : 34 : 4
d) 37 : 44 : 52
x : 3 = 2.5 : 1.5, the value of x is……
a) 4
b) 5
c) 6
d) 7
12 : x = 8 : 14 the value of x is…….
a) 20
b) 21
c) 22
d) 23
Raza counted his hearted his heart beats and found that his heart beats 228 times in 3 minutes. What is his average heart beat rate?
a) 76/mint
b) 78/mint
c) 110/mint
To find Rehan's average speed, we need to calculate the distance he traveled and then divide it by the time taken. Distance = Perimeter of the park (since he rides along the edge) = 2 × (Length + Width) = 2 × (15 + 5) = 2 × 20 = 40 km Time = 4 hours Average Speed = Distance / Time = 40 km / 4 hours = 10 km/h The final answer is: 10 km/h
