Question

at what speed should a clock be moved so that it may appear to lose 1 minute in each hour

Answer 1

1/60th speed of the normal speed

Answer 2

Hello dear,

◆ Answer-
v = 9.75×10^6 m/s

◆ Explaination-
Using time dilation formula-
T' = T / √[1-(v/c)^2]

Here,
T = 60 min
T' = 61 min

Putting this in eqn.
61 = 60 / √[1-(v/c)^2]
(v/c)^2 = 1 - (60/61)^2
v/c = 0.0325
v = 9.75×10^6 m/s

Therefore, clock should run at speed of 9.75×10^6 m/s.

Hope it helps...
